Alfa Laval Rotacheck Sensor Cleaning validation

Introduction

The Alfa Laval Rotacheck Sensor is a cleaning validation

instrument that provides verification of the Alfa Laval Rotary

Jet Head tank-cleaning devices. It is highly accurate at

detecting the sweep and impact of the cleaning media

released by the rotary jet head, thereby providing tank

cleaning quality assurance. This device is suitable also when

there is higher pressure during Cleaning-in-Place (CIP) in the

tank.

Application

The Rotacheck Sensor is designed for use in a tank-cleaning

system that uses rotary jet heads and where the tank is

pressurized during CIP and where validation of hygienic

operation is required across the dairy, food, beverage,

brewery and pharmaceutical industries.

Benefits

• Validation of 360° repeatable cleaning pattern

• Verification of tank cleaning coverage

• Highly accurate detection of the jet sweep and impact

• Improved product quality

Standard design

The Alfa Laval Rotacheck Sensor consists of a stainless steel

IP67-rated casing, sensor, diaphragm, welding adaptor, and

cable for relay connection. As standard ATEX-certified version

is for use in potentially explosive areas. The sensor complies

with Category 1/2 requirements for installation in zones 0/1

and 20/21. The relay complies with Category 2 requirements

for installation in zone 1/21.

Working principle

The sensor of the Alfa Laval Rotacheck Sensor detects the

sweep and impact of fluid jets released as the rotary jet head

performs its cleaning cycle. The system is appropriate

wherever rotary jet heads are employed in cleaning tanks and

where the tank is pressurized during CIP. The signal generated

by the system can be audible, visual or integrated into the

customer’s process control specification.

Based on the geared operation of the cleaning device and

signals recording the impact force from the jets, the sensor

verifies hygienic operation of the rotary jet heads, taking into

account any backpressure in the tanks.

The hygienic Rotacheck sensor is precisely installed to detect

the sweep and impact of fluid jets released as the rotary jet

head performs its cleaning cycle. From the geared operation

of the cleaning device, and by reciving the impact force from

the jets, the sensor provides vertification of hygienic operation.

Any back pressure in the tanks is accounted for.
